Rosa roxburghii Tratt extract is used to prepare the purposes of cell return of spring composition
Technical field
The present invention relates to a kind of health purposes of Rosa roxburghii Tratt extract, are used to prepare especially with regard to a kind of Rosa roxburghii Tratt extract
The purposes of the composition of cell return of spring composition.
Background technique
With the extension of population average age, possess health and the life in old age of high quality become public concern focus it
One, the scientific research about aging is also more paid attention to.The reason of body aging, is numerous, possible in molecule and cell level
Internal mechanism includes that telomere (telomere) shortening, gene mutation, protein synthesis efficiency of end of chromosome be bad, grain wire body
Function reduction, cellular morphology variation etc..In addition, the free radical generated in cell peripheral environment by physical or chemical factors is (as lived
Property oxygen species) can damage chromosomal RNA (DNA), protein and the lipid biomembrane of cell, and individual in response to
Such cellular damage or microorganism invasion and start inflammatory response once develop be chronic inflammation but will aggravate cellular damage, because
This accelerates cell and body aging.
It include that natural is obtained by diet to promote the ability that individual removes free radical to anti-aging method,
And inhibit intracorporal chronic inflammation by anti-inflammatory medicine.In view of the aging origin cause of formation of above-mentioned complexity, designed for simple target
Antiaging method it is obviously ineffective.Although stem cell therapy emerging at present is great anti-aging potentiality, so it is still in
Developing stage, and medical expense is high.Therefore, a kind of simple novel composition is developed, remains individual or thin with complex method
Born of the same parents are in younger state, there is its necessity in fact.

Life or the effect for postponing aging.
Embodiment 4
The shortening of Rosa roxburghii Tratt extract inhibition chromosome telomere length
4.1 confrontation resulted from chemical medicine telomeres shorten
The present embodiment inquires into the water extract of Rosa roxburghii Tratt to the chromosome telomere of human skin fibroblast CCD-966SK
Protective effect.Firstly, CCD-966SK cell is according to 1.5 × 105A cell/disk is inoculated in respectively containing 2mL MEM cell culture medium
Three 35mm culture plates, cultivated at 37 DEG C it is overnight after, take half cell (the 0th day) to be sub-packed in RNA stabilizing solution from each culture plate
(RNAlater solution;Ambion) and -20 DEG C are stored in for later use, remaining cell is then seeded to another three respectively
A 35mm culture plate, it is overnight in 37 DEG C of cultures.Thereafter, the disk cell in the three disks cell relies on Bo Xi with 30 μM of chemotherapeutics
(etoposide) it handles, another disk cell is handled with 30 μM of support Bo Xi and 0.5mg/mL Rosa roxburghii Tratt water extracts, and a remaining disk is thin
Born of the same parents refuse drug and Rosa roxburghii Tratt extract processing and as control group.It was cultivated by 5 days, collects three groups of cells (the 5th day).By
Nucleic acid auto extractive system (tacoTM automatic nucleic acid extraction system;GeneReach
Biotechnology) and accompanying DNA extraction set group (tacoTM DNA/RNA extraction kit) is from aforementioned 0th day and the
Genosome DNA is obtained in 5 days cells collected, and is measured for qPCR and telomere length.As shown in figure 8, relative to control group
Cell relies on the processing of Bo Xi to be obviously shortened the relative length of telomere, but the processing of Rosa roxburghii Tratt water extract can slow down this end
Grain shortens phenomenon, illustrates that Rosa roxburghii Tratt extract can maintain the length of the telomere by chemistry injury.
Telomere caused by 4.2 pairs of uvioresistants (UV) are irradiated shortens
CCD-966SK cell is according to 1.5 × 105A cell/disk is inoculated in three respectively containing 2mL MEM cell culture medium
35mm culture plate, cultivated at 37 DEG C it is overnight after, wherein two disk cells give 1J/cm2 UVA (wavelength 320-400nm) irradiation,
Another disk cell refuses UVA irradiation and is set as control group.Half cell (the 0th day) is taken to be sub-packed in RNA stabilizing solution from each culture plate
(RNAlater solution;Ambion) and -20 DEG C are stored in for later use, remaining cell is then seeded to another three respectively
A 35mm culture plate, it is overnight in 37 DEG C of cultures.Thereafter, which is pierced through the disk cell in UVA irradiating cell with 0.5mg/mL
The processing of pears water extract, another disk cell are disregarded.By secondary squamous subculture and aforementioned ultraviolet light irradiation is repeated every time to walk
Suddenly, three groups of cells (the 7th day) are collected.By nucleic acid auto extractive system (tacoTM automatic nucleic acid
extraction system;GeneReach Biotechnology) and accompanying DNA extraction set group (tacoTM DNA/RNA
Extraction kit) genosome DNA is obtained from aforementioned 0th day and the 7th day cell collected, it is long for qPCR and telomere
Degree measurement.Fig. 9 shows that Rosa roxburghii Tratt water extract irradiates the inhibiting effect that caused Skin Cell telomere shortens to ultraviolet light.Such as Fig. 9 institute
Show, relative to control group cell, UVA irradiation is obviously shortened the relative length of telomere, but the processing of Rosa roxburghii Tratt water extract can
This telomere is greatly decreased and shortens phenomenon, illustrates that Rosa roxburghii Tratt extract can maintain the length for the telomere being damaged by ultraviolet light, i.e. Rosa roxburghii Tratt extracts
Take object that there is anti-light aging effect.
In conclusion above-mentioned experiment shows that Rosa roxburghii Tratt extract can reduce cellular damage caused by oxidative pressure or inflammation simultaneously
And the normal operation of gene, protein and grain wire body is maintained, and can increase telomere enzyme reaction and reduce telomere because of chemicals
Or ultraviolet light is irradiated and is damaged, and eventually leads to the effect of the cell return of spring.Therefore, the present invention provides Rosa roxburghii Tratt extract and is used to prepare carefully
The purposes of born of the same parents' return of spring composition, the composition can be powdered, graininess, liquid, glue or paste, and can be made into food, drink
Product, drug, reagent or nutritional supplement give an individual by modes such as oral, dermal applications.
